' ATo all 'whom it may concern: Be itgknown that I, ERNEST E. HE1NTZ',

a. citizen of the'United States,"residing Aati Detroit, inthe county'ofjWayne and State 5 -of Michigan, have invented certain-new and useful Improvements in Handle A mblies,

cfg-which the following is a specification.

This invention relates to handle-construc-4 -tion and has .for its object, a, cheaper, simple 1o but' effective way for fastening a. cran handle to a spindle. It is especially designed and adapted for' lfasteninga crank handle upon the spindle of -a window regulator.'

In the drawings: 1 j Fig. 1 is a cross section of a-'window 'regulator showing the handle vin place.

' .,Fig. 2 is a section of a handle .adjacent thehub.

3 is 'a section on the`v line 3-3 of Fig.

' comes a bearing and when the escutcheonplate is fastened to the window regulatorhousing, the`hub of the handle with a squared opening fits over the squared end of the regulator spindle. This makes a very satisfactory and neat job, but is relatively expensive. It is the`5"obj".t of the present invention to aii'ord a satisfactory 4o fastening which is much cheaper and intended for the low priced regulators `designed for low priced cars.

Referring to the drawings, 1 designates the handle which is blanked out; in a stamping operation. This is provided with a hub bhaving a central serrated or toothed open- 'ing c. The teeth are relatively line for 'a purpose hereinafter to be described. The' escutcheon can be simply a thimble e, fitting 5- 0 up a ainst 'the trimming f," g designatestheA reg ator casing, or for that matter,'n0 casing need be employed, the o ing rts of the regulator being simp y carri regulator plate.

onthe" .out of the reg\1 t5 lator is the spindle which runs into theI clutch housing 'j to operate 'the clutch parts.

in a. waythat'is familiar. A variety of dif Vferent formsl of clutch can be used," and hence it is unnecessary-to describe .the 'clutch con: struction., ou. This regulator spindle shownein detail v in Fig. 4.-- -It is 'ai screw machine product comprising -astud-niember'k, provided with a. key ningen, flattened-"'on'bneside as, at

is calculated to turn. The'outer. end of the spindle 'is toothed'or serrated as at o; it`is alsol ollow and slotted as at p.' -Furthermore, .the interior is tappe as 'at to 'receive .the screw stud r which is a. special automatic A screw machine product. The inner end ofA this screw is threaded like a'lny other machine screw, but it hasfan'elongated head 19' which is also threaded aswell as slotted as att, for the4 screwdriver. This elongated head is is 75 connected fwith the reduced-portion f the screw vby a.- tapered shoulder or a cone u -whic'h I callthe spreader or expandingportion. This is adapted to beara inst the tapered or countersunk portion o theV 4split 580 end-.ot the spindle. :Obviously when ythe screw is screwed into the split end of the spindle, the portions engaging serve to expand the end of the spindle. ig

The end i of.- 4the -Screw 1 is externallft threaded lo receivethe blind nut If in-f? stead of using the blind nut, a cap screw is used, my purpose would not be as. well accomplished for the reason that if the head of thel cap screw were to lie 'tightly upg() against the hub of the handle it 'wouldbe found that 'the screw had been stopped b elfore the expansion'had been completed. By

my arrangement of a .separate'screw'and blind nut, it is possible to turn the screw-to any depth to get; the required expansion and then put on the blind'nutand turn this tightly' down.

` By using the expansion spindleI am able to use relatively fine teeth whichwould not 10c otherwise be possible as the teeth would -in the course of time wear so as to let the hub turn thereon. r By using the ex ansion prin- "ciple theteeth are so firmly imhedded in the substance of the hub that there is no chance 1o: of their eve`i` coming loose to turn. By us ing the fine teeth I am enabled to get the handle at any angle so' as to accommodate Ithe handle to the `regulator parts. i

use expansion-'screws I and'fboitsgthatthey are' common in wall construction fand other places, but'so-far as I am aware, they have not .been used-for'the purpose here in View .and they accomplish aA new' and improved result in tying a, toothed spindle' toatoothed handle-hub in -sucha way Aas to permit the handle to be placed upon the spindle 'atr-almost any angle.; due to the fine teeth that can be employed.
